ATTORNEYS Patented Mar. 12, 1935 VENTILATED EYE GOGGLE Application April 9, 1932, Serial No. 604,175

6 Claims.

In eye goggles it is customary to provide ventilation by gratings or openings directly through the cup-walls at points around the side, top or bottom. Complaint has been made however, that this occasionally allows small metal particles, etc. to strike the eye of a user. A construction which can obviate this danger and yet maintain ventilation is accordingly of fundamental importance and highly desirable.

To the accomplishment of the foregoing and related ends, the invention, then, comprises the features hereinafter fully described, and particularly pointed out in the claims, the following description and the annexed drawing setting forth in detail certain illustrative embodiments of the invention, these being indicative however, of but a few of the various ways in which the principle of the invention may be employed.

In said annexed drawing:-

Fig. 1 is a plan view of an eye gogggle cup embodying the invention; Fig. 2 is a vertical section of the same, taken on a plane substan tially indicated by the line IIII, Fig. 1; Fig. 3 is a front elevational view of a goggle cup with the cap-ring removed; and Figs. 4, 5 and 6 are fragmentary sectional views of modifications.

Referring more particularly to the drawing,

with direction such that flying metal particles, etc. cannot directly strike through into the eye.

In the form of construction shown in Fig. 4, the channels 6a are formed in the cap-ring 5a instead of in the cup. The cup may have forwardly-directed projections 2 to hold-the glass sufficiently spaced away as to not block the airchannels, and with the ring assembled in place these again constitute unobstructed openings from the rear forwardly between the cup and ring.

If desired, the cup may be formed with an anterior raised 'rim or exaggerated peripheral enlargement 7, and the openings or channels 61) may be provided through such'rim, the openings being in the form of bores or grooves as may be preferred, affording air pass-ways having a direction such as to lie generally as in the forms described foregoing. The cap-ring 5b completes the assembly, and a thin spacer-ring 8 may be interposed to hold the glass G at a spaced distance and prevent blocking of the air passages. 0r, instead, as shown in Fig. 6, the spacer'may be eliminated and the channels 60 may be directed at such an angle as to give clearance inside the glass.

In whatever detail form, it is thus seen that there is shown an eye goggle cup 2, which may ventilating openings are available in a manner vary as to its precise form and detail, but which in general is of a shape adaptable to seat over the eye of a user, and joined to a similar cup by bridge or connecting means 3 of usual or desired detail, and having temple bow or holding means 4 in particular form as preferred. The anterior portion of the cup is closed by a glass G as usual, and a cap-ring 5 completes the assembly. Directed from the rear forwardly are ventilating openings or channels 6, and in the form shown in Figs. 2 and .3, these are in the nature of grooves or channels spaced around the periphery of the cup 2, such as to come under the assembled cap-ring 5, and present an outer opening 6 at the rear thereof for inlet of air, and extending thence in a direction toward the glass to an inner opening 6". By screw-threaded arrangement between the cup 2 and the ring 5, assembly is particularly well facilitated, and the channels 6 thereunder are guarded and provide ventilation in the assembled structure. These channels may be formed by suitably contoured dies in the molding, if the cup be made of molded material,

to avoid possibility of metal particles and the like striking directly through into the eye of the user. At the same time, the structure of the goggle cup generally need not be materially changed or diverted from lines of desirable manufacturing form.

Other modes of applying the principle of the invention may be employed, change being made as regards the details described, provided the means stated in any of the following claims, or the equivalent of such, be employed.

I therefore particularly point out and distinctly claim as my invention:

1. An eye goggle, comprising a goggle-cup, a lens-holding ring screw-threaded thereon, and means for introducing air in a direction forwardly and tangentially, said means including safety ventilating openings in the form of channels between the cup and ring starting at the rear of the ring and extending spirally and convergingly through to open inside the lens.

2. An eye goggle, comprising a goggle-cup, a lens-holding ring screw-threaded thereon, and

or the channels'may be out after the formation safety ventilating openings in the form ofchanof the cup. However formed, their arrangement is such as to allow assembly of the cup and ring, and leave the bores or channels therebetween nels cut through the screw threads of the ring from the rear forwardly to open inside the lens.

3. An eye goggle, comprising a goggle-cup, a V

ing a raised rim throughout its circumference, a

lens-holding ring screw-threaded on such-raised rim, and safety ventilating openings in the form of channels'at least in part insaid rimdirected from the rear forwardly to open inside the lens.

6. An eye goggle, comprising a goggle cup hav ing a raised rim throughout itsrcircumferen ce,

a, lens-holding ring screw-threaded on such raised rim, and safety ventilating openings in the form of channels directed from the rear forwardly in such raised rim. 7 1
